Oscar Winners: Whose Next Role is the Most Enticing?

Winning an Oscar doesn't immediately make a Hollywood career. It's not a sudden yellow-brick road to critically beloved superstardom. Aside from the many who seem to fade into an oblivion of bad choices (see Halle Berry), there's the whole challenge of timing. Each winner has prior commitments and pre-win productions that screen after the little gold man heads home with them.

We're already trying to reconcile the fact that Natalie Portman, Oscar winner, is also Natalie Portman, Ashton Kutcher's latest romcom beloved in 'No Strings Attached.' But what about the films to come? What's next on the pike for each of the four Oscar winners this year? Melissa Leo, Christian Bale, Colin Firth and Portman herself?
